Synthesized from 6 studies in the library · AI-generated, grounded in the abstracts below
Found by searching the library for Default mode network, DMN, resting-state network, then ranked by relevance.
Research in March 2026 found that LSD induces a frequency-selective decoupling of the default mode network (DMN) from structural brain constraints, with gamma-band decoupling in core DMN regions specifically predicting ego dissolution. A systematic review of psilocybin fMRI studies noted that most research has focused on regions like the amygdala and prefrontal cortex, but highlighted inconsistency in methods and designs. The evidence is limited by the small number of studies directly addressing the DMN in March 2026 and the methodological variability noted in the review.
Confidence in the evidence
Low- Only two studies directly address the DMN: one original MEG study on LSD (article_id: 24912) and one systematic review on psilocybin (article_id: 27875).
- The LSD study is a single original experiment, not a meta-analysis, and the psilocybin review highlights high dropout rates and lack of follow-up scanning.
- The other four studies (article_ids: 29789, 29791, 31065, 29570) are reviews or theoretical models that mention the DMN but do not provide new empirical findings from March 2026.
- The psilocybin review reports inconsistency in methods and designs across studies, limiting confidence in any single conclusion.
How we rate confidence
Confidence reflects the strength of the underlying evidence, not whether the result is favorable. It weighs the number and size of studies, their design (randomized trials count for more than observational or single-case work), how consistently they point the same way, and their risk of bias.
Tiers run from Insufficient to High. High is rare in this field: small, early, or open-label studies land lower even when their direction is encouraging.
Evidence by study
Direction is each study's finding relative to your question: Supports, Opposes, No effect, Mixed, or Unclear.
| Study | Design | Sample size | Direction | Finding |
|---|---|---|---|---|
| Psilocybin effects on brain functional connectivity: a systematic review of fMRI studies 2026 | systematic review | 20 | Unclear | The review found that most psilocybin fMRI research has focused on the amygdala, anterior cingulate cortex, and prefrontal cortex, but methods and designs are inconsistent, and follow-up scanning timepoints are lacking. |
| The Neuropeptidergic Modulation of Phenomenological Depth: A Review of Oxytocin’s Role in Facilitating States of Pure Consciousness 2026 | review | Unclear | This review proposes that oxytocin modulates the DMN to facilitate non-dual awareness, but does not present new empirical data from March 2026. | |
| Neural dynamics of mindfulness training: A longitudinal EEG network analysis of focused attention and open monitoring meditation 2026 | longitudinal EEG network analysis | 16 | Unclear | This study analyzed EEG network dynamics of mindfulness training but did not directly investigate the DMN. |
| Hypnosis as a Mechanism of Emotion Regulation and Self-Integration: An Integrative Review of Neural, Cognitive, and Experiential Pathways to Fundamental Peace 2026 | integrative review | Unclear | This review discusses how hypnosis modulates the DMN, executive control network, and salience network, but does not provide new empirical findings from March 2026. | |
| LSD Relaxes Structural Constraints on Brain Dynamics and Default Mode Decoupling Tracks Ego Dissolution 2026 | original MEG study | Supports | LSD induces a global decoupling of low-frequency activity from anatomical constraints, and greater gamma-band decoupling within core DMN regions predicts the intensity of ego dissolution. | |
| A Neurophilosophical Model of Personal and Meta-Reflective Modes of Mind 2026 | theoretical model | Unclear | This paper proposes a neurophilosophical model distinguishing personal and meta-reflective modes of mind, but does not present empirical data on the DMN from March 2026. |
The review found that most psilocybin fMRI research has focused on the amygdala, anterior cingulate cortex, and prefrontal cortex, but methods and designs are inconsistent, and follow-up scanning timepoints are lacking.
systematic review Sample size: 20
This review proposes that oxytocin modulates the DMN to facilitate non-dual awareness, but does not present new empirical data from March 2026.
review
This study analyzed EEG network dynamics of mindfulness training but did not directly investigate the DMN.
longitudinal EEG network analysis Sample size: 16
This review discusses how hypnosis modulates the DMN, executive control network, and salience network, but does not provide new empirical findings from March 2026.
integrative review
LSD induces a global decoupling of low-frequency activity from anatomical constraints, and greater gamma-band decoupling within core DMN regions predicts the intensity of ego dissolution.
original MEG study
This paper proposes a neurophilosophical model distinguishing personal and meta-reflective modes of mind, but does not present empirical data on the DMN from March 2026.
theoretical model
Points of agreement
- Both the LSD study (article_id: 24912) and the psilocybin review (article_id: 27875) implicate the DMN in psychedelic-induced alterations of consciousness.
- The LSD study and the oxytocin review (article_id: 29789) both suggest that DMN modulation is linked to ego dissolution or non-dual awareness.
Conflicts
- The psilocybin review (article_id: 27875) notes inconsistency in methods and designs across studies, which may conflict with the specific findings of the LSD study (article_id: 24912) if different methodologies yield different results.
- The theoretical model (article_id: 29570) does not directly address the DMN, so it neither conflicts nor converges with the other studies.
Gaps
- No studies in March 2026 directly examine the DMN in clinical populations or with longitudinal follow-up.
- The psilocybin review (article_id: 27875) highlights high dropout rates and lack of follow-up scanning timepoints, indicating a gap in durability of effects.
- The LSD study (article_id: 24912) does not report sample size, limiting assessment of statistical power.
- No studies compare different psychedelics (e.g., psilocybin vs. LSD) on DMN decoupling in the same experimental design.
